charged is no danger at any time of the accumulation of gas .and attendantdanger of explosion, which has been found to occur with various types-oi" commercial storage batteries.

The plates 'or electrodes are practically ree from liability of iiaking, crumbling or buckling, and hence are correspondingly tres from faults prevalent in storage batlteries.

lnlthe assembled battery, sheets of cardboard or strawhoard or similar material impregnated with oil or. some other similar substance have been found efficient as separators, permitting very close approach of 'the plates, and, as the plates do not buckle or swell, such cardboard separators are found to completel answer the purpose. also because the p etes do not buckle or swell or flake or crumble, it is possible to employ simple strips as separators. The cardboard separators, however', are preerred.

When the plates are first baked the paste liller ont the grids is hard and compact and become', harder each time the battery is and discharged.,

Various advantages ascribed to the battery are based upon actual experience throughtrials extending over a protracted period.- 'y

Experience has shown that the glycerin employed tends to harden the plates, the iron chlorid prevents gassing and bubbling, and the aluminum sull-ate appears to reduce the internal resistance, since the output o't the battery is considerably reduced when the aluminum sulfate is omitted.

Tests have demonstrated that the output lo' the battery may reach about one ampere per square. inch of electrode surface on maximum discharge and this Without harm to the electrodes.

lt has been found trom actual test that f the electrolyte holds up under long use and many rechargings, requiring only the addition oi' Water which latter need not be distilled Water, The additional Water is only necessary to replace the Water lost by evaporation or Jrom other causes, so that the electrodes may remain covered with the electro- What is claimed iszl.
